To all whom it may concern.'

Be it known that I, C HARL SJGREN, a

citizen of the United States, residing atl Wessington Springs, in the county of Jerauld and State of South Dakota, have inventeda new and useful yVehicle-W'heel, of which the following is a specification.

This invention relates to vehicle wheels and is more especially designed as an irnrovement upon the structure disclosed in gatent No. 1,059,401, issued to me on April y22, 1913.;

Oneof the objects of the invention is to provide va wheel the parts of which can be cheaply manufactured, readily assembled, and which will not become displaced Irelative to each other, the means employed for providing resiliency being full-y protected at all times.

"With the foregoing and other objects in 'view which will appear as the description proceeds, the invention resides in the combination and'arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that .changes in the precise embodiment of the ,inventibn herein disclosed, can be made within the` scope of what is clain1ed,`\\f'ith out departing from .the spirit of the invention.

r In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a side elevation of a Wheel embodying 'the present improvements, parts being broken away, and certain parts being shown in section. Fig. 2 is a section on line A-B Fig. 1, said section being on an enlargedscale. Fig. 3 is 'an enlarged section on line C-D Fig. 1. Fig. L1 is an enlarged section on line E-F Fig. 1. l

Referring to the figures by characters of lreference l. and 2 designate opposed plates which can be formed of sheet steel or the like and which are pressed and cut to forni the wheel body made up of inner laterally offset rings 3, intermediate channeled portions 4: and outer annular rings 5 which are offset laterally.' The inner 'rings 3 coperate to house a hub y'ring (3 formed of fiber or any other suitable material, there being a reinforcing wear ring 7 upon the outer faces of the offset portions 3. The parts 3, i3 and 7 may be held together in any suitable manner, as by means of transverse bolts 8, The radiallv extending channel portions 4 .co-

operate with each other' to form spokes, as shown particularly in Fig. 1, while the olfset annular rings 5 cooperate to form an annular channel 9. Seated in the innermost portion of this channel 9 is-a bearing ring .10 concave-convex in cross section and havlng an inwardly extending flange 11 which is fitted between the inner portions of the rings 5. Flange 11 and the inner portions of the rings 5 may be held together' in any manner desired, as by means of`bolts 12 preferably located between the spokes as shown in Fig. 1. A channeled rim 13 is eX- tended around and spaced from the offset rings 5 and is substantially concentric with these rings. Said rim 13 is provided with a tire 14 ofany desired material. Secured to the inner face of the channeled rim at regular intervals are brackets 15 and arranged at opposite sides of the brackets are rings 16 and 17 preferably formed of sheet metal. The inner edges of these rings are offset as at 18 to form an annular seat concavo-conf vex in cross section and which is spaced from but disposed oppositely to the ring 10. The

outer' portions of the rings 16 and 17 are offset laterally as at 19 and then extended along para lel lines, thus to form a deep channel 20. he offset portions 5 of the disks 1 and il receive ther-ings 16 and 17 between them and fitted snuglywithin the channel 20 is a cushioning ring 21 preferably formed of rubber. Another cushioning ring 22 is fitted snugly upon the ring 1() and within the seat formed by theoffset portions 18. The youter edges of the rings 1C and 17 fit snugly against the inner face of the rim 13 and are heldagainst lateral displacement relative to the rim by the brackets 15.

Those portions of the rings 1G and 17 forining the walls of channel 20 are provided at regular intervals with elongated openings 22 the end walls of which preferably divergeinwardly to forni deiectors E28. The inner and outer walls of the openings are concentric with the rim 13.

lllovably mounted in the channel Q0 and bearing inwardly against the resilient ring 21 is a tubular ring Said ring 211s preferably rectangular in cross section and seated `in those portions of the ring exposed through the openings '22v are cushioning blocks of rubber` or the like preferably held in placeby bolts 26 extending trans- Y versely tl'irough the tubular ring. llaclrbolt is disposed between.- longitudinal slots 2l' farmed in the sides if the tubular ring, alla slidably mounted in these slots 27am-cross pins' 28 extending through compressing lins28 project into the opening`s22 and mounted for rotation on theends of these pins are rollers 30 whichy are supported freely in the openings 22.

Fitted inQthe wheel at the outersides of the rings 16" and 17 are'guard rings 31 and- 32 bearingsnugly against the inner face of the rim 13.' These lguard'arings have sockets 33 in their outer faces and close to rim 13, one of said sockets being adapted. to receive' the heads 34 of. bolts while the other socket is adapted to receive nuts 36 engaging the bolts.' The bolts 35 extend transversely through the rings 16 and 17 and through the'brackets 15 and thus serve to fasten together the rings 1 6, 17, 31 and 32 and to attach them to the rim 13 by engaging bracket's'l. The inner edges of the rings'- 31 and 32 carry rings 37 of fiber or other suitable material slidably engaging the outer faces of therings 16 and'17and thus serving to'prevent the admission of dust, moisture, etc., intov the space between the I guard rings 31 and 32.

-into the offset portions 5 of thedisks 1 and 2 so as thus to hold the ring 24 against'rotation within the channel 9. These bolts 26 have spacing washers 39 mounted upon l ythem between the sides of ring 24 and thev sides of 'the channel 9, thus to prevent the.

v rallers 30 from binding laterally against the a this limit. of v ring 24 or the walls of channel 9.'

It will be apparent that bolts'35 'will hold the rings 16 and 17 against rotation relative to the rim 13 and, as bolts 26 are secured to the offset portions 5 and the disks '1 and 2 and extend through the ring 24, ,said riiig 24 will beheld against rotation independh ently of the disks'l and 2. Ring 24' will be allowed a limited rotation relative to the rings 16 and'17 due to the size of the openings 22, but "it will .be obvious that when independent rotation reached, one set' of rollers 30 will strike against the adjacent inclined -endwails of the openings 22 with the result thatf the blocks 29 to which said rollers are connectedwyill be thrust-longitudinally ofthe ring 24 and thus pressed against the cushioning block 25. The cushioning rings 21 and 22 obviously provide the desired resiliency in the wheel, the placing of a load upon the Wheel resulting in a downward thrust through ring 10 upon the cushioning ring(` 22. Furthermore this downward thrust causes the upper portion off/'thev tu` bular ring 24 tov press downwardly on the 5 upper portion of the cushioning ring 21. blocks 2 9 slidably mounted in the ring 24.'y f
